BIGLKNM Primary Gasket Kit for Road King, Street Glide & Electra Glide 2007–2017 — Complete OEM-match Seal Set

BIGLKNM Primary Gasket Kit is a complete seal and gasket set designed to restore the primary cover, derby cover and oil seals on Twin Cam bagger models from 2007–2017.

When your Harley-Davidson Road King, Street Glide or Electra Glide shows signs of primary cover seepage or you’re rebuilding the primary area, having the correct gaskets and seals matters. This BIGLKNM kit gathers the inner primary gasket, foam primary gasket, both oil seals, the ribbed derby (clutch cover) seal and the small O-rings used on screw holes into one package so you can replace all wear-prone parts in one service. The parts match common OEM part numbers used on Twin Cam baggers, making it a practical choice for preventative maintenance or repair.

Which models and years does this gasket kit fit?

This kit is made for Twin Cam bagger platforms produced 2007 and later, specifically Road King, Street Glide and Electra Glide models up through 2017. It is not intended for Softail motorcycles or other engine/platform types. Before ordering, confirm your motorcycle’s model year and engine type to ensure compatibility.

• Fits: Road King, Street Glide, Electra Glide (Twin Cam baggers) 2007–2017
• Not compatible with Softail models
• Matches common OEM numbers for straightforward identification
• Designed for primary cover and derby (clutch cover) service

What parts are included in the BIGLKNM primary gasket kit?

The kit includes the inner primary gasket, two specific oil seals, a ribbed silicone derby gasket (clutch cover seal), a primary foam gasket, and two small O-rings for screw holes. These components replace the most commonly failed sealing surfaces in the primary cover area to reduce leaks and ensure proper fitment during reassembly.

• 1x inner primary gasket (34934-06)
• 1x foam primary gasket (34901-07)
• 1x ribbed silicone derby (clutch cover) seal (17369-06)
• 2x oil seals (12052A and 12066)
• 2x O-ring screw-hole seals (63859-95B)

How will this kit help during a primary service or rebuild?

Replacing all primary-area seals at once minimizes the chance of repeat leaks and saves time over sourcing parts individually. Using the correct-profile gaskets and new oil seals restores proper sealing surfaces and helps maintain oil containment and correct lubrication paths inside the primary.

• Prevents common seepage points after cover reinstallation
• Ensures correct seal fit and compression for reliable sealing
• Reduces hassle by providing all needed primary seals together
• OEM-number matched pieces simplify part verification

What should I check before installing this gasket kit?

Inspect the primary cover faces for warping, deep scratches, or damage that gaskets alone can’t fix. Clean mating surfaces thoroughly, replace any damaged fasteners, and confirm the oil seal bores are within tolerance so the new seals seat correctly.

• Verify your bike is a Twin Cam bagger from 2007–2017
• Check mating surfaces for flatness and damage
• Use recommended torque specs and new fasteners where needed
• Clean all surfaces and remove old gasket residue before assembly

Who is this kit for? Mechanics, DIY enthusiasts and professional shops working on Harley-Davidson Twin Cam Road King, Street Glide and Electra Glide models from 2007 to 2017 who need a convenient, OEM-number-matched set of gaskets and seals for primary cover repairs. If you’re doing a primary service, replacing a leaking derby cover, or performing a clutch or transmission service on the specified bagger models, this BIGLKNM kit provides the core sealing components you’ll likely need to complete the job efficiently.
